Abstract

Itchy skin and pruritus are two of the most common symptoms of Atopic Dermatitis (AD), which is characterized by flares and remissions that occur on a regular basis (Spergel, 2010).


Many theories have been advanced in reference to the development of inflammation that results in AD's disease. The first implies that there is a basic immunological malfunction that results in IgE sensitization, allergic inflammation, and other symptoms. Specifically, the primary immune dysfunction hypothesis proposes that there is an imbalance in T cell subsets, with Th2 cells predominating; this results in the production of type 2 cytokines such as interleukin (IL)–4, IL-5, and IL-13, which leads to an increase in IgE from plasma cells and a secondary epithelial barrier disruption. The second hypothesis posits that there is a fundamental abnormality in the epithelial barrier, which results in subsequent immunologic dysregulation and inflammation. The following medications are often used to treat AD 's disease. Hydrocortisone, triamcinolone, or betamethasone are the most often used steroids. Tacrolimus is animmunomodulator with a broad spectrum of activity.


Vitis vinifera, one of the world's most widely eaten fruits, includes a number of


active components, including organic acids, lipids, and polyphenols.


Grape polyphenols inhibit inflammation by regulating inflammatory pathways and reducing reactive oxygen species (ROS). Grape flavonoids and proanthocyanins combat inflammation better than synthetic drugs.
